The anti-mainstream opinion, Just do it once before you die and after that time there will be no chance again.

Some time ago I also made a T-shirt Design for Coinomize's Bitcoin Mixer Platform and many liked the design and even Coinomize sponsored it.

I wore it last week at the Car Freeday event, and there was no response whatsoever about the shirt I was wearing.
Just a few pranksters scanning barcodes to find out what's on my back.

Where I live or in the city I live in, Bitcoin is not very popular and no one even notices the T-shirt I use.
The average of them considers Bitcoin as a worthless digital currency, just like a Ponzi scheme, MLM and others.
There is no threat to the use of T-shirts with the Bitcoin logo or anything like that at my place.
It's been quite an exciting experience, which others say looks extreme.
